摘　　要：针对传统压风机系统整流、逆变单元功率不匹配造成的母线电压波动问题,提出一种基于平均电压约束的矿井压风机系统母线电压平抑方法。该方法在引入平均电压概念的基础上,利用了永磁同步电机无功功率支撑特性,在不影响输出压风机机械功率特性的基础上,实现整流、逆变侧功率的有效平衡。基于35 k W的矿井压风机调速系统实验平台,对所提母线电压平抑方法进行验证与分析。Traditional air compressor system rectifier, inverter unit, power mismatch caused by voltage fluctuations, is presented based on the average voltage constraints of bus voltage stabilizing method for mine air compressor system. On the basis of the method to introduce the concept of average voltage,using the characteristics of PMSM reactive power, without affecting the output air compressor mechanical power based on the effective balance of the rectifier, inverter power. 35 kW mine air compressor speed control system of experimental platform for validation and analysis of the proposed bus voltage stabilizing method.
